[Qgis-user] Clip Raster by Mask Layer algorithm not working when part of processing model

[Phil Ribbens]

Hi,

I'm trying to include the “Clip raster by mask layer” algorithm in a processing model, but I can’t get it to work. What’s weird is that when I run the algorithm by itself (i.e. not as part of a model), it works fine.

Below are the logs of each (when I run it by itself and when I run it as part of a model). From studying these it seems like the only difference (and what seems to be causing the problem) is that when the algorithm is run from within a model the path to the MASK layer isn’t being included in the GDAL command. Anybody have any idea why? Am I doing something wrong? Is it a bug? 

Thanks,
Phil Ribbens
